According to DATSC.com, OBD Code P0126 is usually triggered by a low coolant level, a faulty engine coolant thermostat or a poor connection between the electrical circuit and the engine coolant temperature sensor, or ECT. The error code 0300 can vary if the problem is specific to a single cylinder. The final digit of the code, if a number other than zero, refers to the cylinder where the problem is detected. For example, 0301 refers to a detected misfire at cylinder one. Possible culprits are a faulty spark plug or ignition coil, incorrect fuel pressure, intake air leak or clogged fuel injector, according to AutoCodes.com.
